堆高车驱动轮速度明显降低或驱动电机严重过载：原因：电池电压太低或桩头接触电阻太大；电机换向器片间积碳引起片间短路；电机制动器调整不当而使电机带制动运行；驱动头齿轮箱及轴承缺少润滑或底座卡阻；电机电枢短路。解决方法：检查堆高车负载时电池端电压或清洗桩头；清理换向器；调整制动器间隙；检查清洗并重新加注润滑油，**卡阻现象；更换新电机。
Forklift truck driving wheel speed decrease or drive motor overload causes: the battery voltage is too low or the pile head contact resistance is too large; the motor commutation carbon caused by short-circuit between plates; improper adjustment of the motor brake motor with brake operation; driving head gear box and the bearing base resistance or lack of lubrication card; motor armature short-circuit. Solution: check the battery load at the end of the stack truck or clean the pile head; clean the commutator; adjust the brake clearance; check, clean and refill the oil, remove the obstruction; replace the new motor.
　三月，醉一场青春的流年。我们珍惜三月，就像我们珍惜来之不易的幸福青春。三月的雨，三月的风，三月的春光，三月的花香，让我们沉醉不知归路，兴尽晚回舟。在这样一场盛大而清新的流年，我们懂得，青春是一种一去不复返的风景，应当好好保护；青春是一种美丽而活跃的热情，我们必须耐心保持；青春是一种来之不易的懂得，我们必须细心呵护。
